How the VAT and sales tax calculator works
Choose whether your entered amount is a net price (tax not yet included) or a gross price (tax already included). Enter the applicable tax rate as a percentage, and the calculator instantly shows the net amount, the tax amount, and the gross amount. This works for VAT, GST, HST, sales tax, or any flat percentage tax.
Removing tax from a gross price uses the formula net = gross / (1 + rate), which correctly reverse-calculates the tax that was embedded in the headline price. Simply subtracting a percentage from the gross would give the wrong answer.
FAQ
What is the difference between net and gross? Net is the price before tax; gross is the price including tax. Invoices typically show both.
Which rate should I use? Use the rate applicable in your jurisdiction for the type of goods or services. Common standard rates are 20% (UK), 19% (Germany), and 10% (Australia). Sales tax in the US varies by state and locality.
